Definitions
- the present invention relates to a method for producing a rolled edge from an edge section of a tube, in which a flanging die moves into the edge section and flanges it into a roll.
- FIG. 1 shows a longitudinal section of an aerosol dome 10 with a tube section 11 and a flanging die 21 with a radius 22 of a forming tool 20 (not shown in further detail).
- On the left-hand side of FIG. 1 is the initial state with the as yet undeformed tube section 11 and the flanging die 21 shown in its starting position.
- the right part of Fig. 1 shows the flanging die 21 in its end position.
- FIGS. 2a) - 2e) each show details of the rolling process in an enlarged section A of FIG. 1.
- the transition from FIG. 2a) to FIG. 2b) recognizably results in the formation of a practically rectilinear starting zone 14, the mentioned bend 13, which disadvantageously remains in the further forming process according to FIGS. 2c) - 2e).
- the initial zone 14 represents an uncontrolled geometry zone. It leads to a variable height H (see FIG. 2e) of the rolled edge 12 and thus also to an uncontrolled, irregular edge geometry 15, as is shown in FIG. 3 in a partial view of the reshaped aerosol domes is shown.
- the invention proposes in a method of the type mentioned at the outset that an initial zone of the edge section with the flanging die is first rolled in a form-fitting manner by an automatically controlled tool before the rolled edge is actually manufactured.
- the sheet already has a controlled geometry with the desired radius in the critical starting zone. Kinking is avoided. In the subsequent forming step, it is possible to produce a rolled edge that is more regular and constant in its geometry.
- Controlled rolling also causes tensile stresses caused by the expansion of the sheet during rolling to spread more evenly over the circumference distribute the sheet edge and thus the risk of radial cracks in the sheet is reduced. This increases process reliability, which is particularly important and advantageous again in aerosol dome production.
- Fig. 4 in a longitudinal section an aerosol dome with a tube section in one
- Roll-on tool in two positions, namely undeformed on the left and fully rolled on the right;
- Figure 5 is a plan view of the rolling tool.
- Figure 6 a corresponding representation of an aerosol dome and a
- Flaring stamps in two positions, whereby one of the aerosol domes, however, has an already rolled-up initial zone;
- an aerosol dome with a tube section 11 is again designated, which, however, is placed here in a rolling tool 30.
- This comprises a roll-on punch 31 with a radius 32, at least one hold-down 33, a plurality of counterholders 34 and a corresponding number of sliders 35.
- the counterholders 34 can be designed as four radially movable segments which together delimit or release a circular opening.
- the initial state with the still undeformed pipe section 11 and the roll-on punch 31 is shown in its starting position.
- the parts 33 - 35 are, however, already in their end or functional position.
- the hold-down device 33 moves down together with the counter-holders 34 as far as it will go with an annular rim 16 of the aerosol dome. Then the slider 35 are moved down to the hold-down 33. By being coupled to the counter-holders 34 via an inclined surface, they push the counter-holders 34 radially inwards into the end position shown for the stamping process.
- the right part of FIG. 4 shows the roll-on punch 31 in its end position. When the roll-on punch 31 is moved between its start and end positions, a start section 14 of the pipe section 1 is rolled on and provided with the radius 32. Then the roll-on ram 31 is withdrawn again from the tube section, the slides 35 are moved upward, the counterholders 34 are moved radially outward, the hold-down device 33 is moved upward and the aerosol dome 10 is thereby released.
- the aerosol dome 10 or its tube section 11 can then be further shaped analogously to the method already explained with reference to FIGS. 1 and 2, FIG. 6 showing a representation corresponding to FIG. 1.
- the rolled-on starting zone 14 of the pipe section 11 already fits flush with the radius 22 of the flanging die 21 in the starting position shown on the left.
- the radii 22 of the flanging die 21 on the one hand and 32 of the rolling die 31 are preferably dimensioned the same.
- the initial zone 14 maintains its controlled radius, as is shown in the detailed illustration B of FIG. 6 in FIG. 7, which shows the finished rolled section. NAME LIST
